Water Cress

People always tell me how much they love watercress (Nasturtium officinale) yet I dont know anyone who grows it, they are all too scared that it would be too difficult.  Everywhere I read says that water cress is difficult to grow.  Many places claim that water cress requires crystal clear water and that without flowing water it will not grow.  This is simply not the case, water cress is easy to grow if you have water, sunlight and soil.

I have wanted to grow water cress for years but was scared that it would not go well.  Having no one to ask adds to the fear that it would be difficult to grow.  Having never grown watercress meant that I had also never eaten it.  I was very curios about eating watercress so decided to bite the bullet and grow some.  One day I ordered some water cress seeds from ebay (something I never like to do as there is no guarantee with seeds, but it was so cheap it was worth the risk) and decided to give it a go.  I tried to grow it in a few ways and surprisingly all of them grew well.  It grew so well and was so simple that I thought I should write a post about it and explain what I did so that hopefully some other people will also give it a go.

Watercress starting to flower

Watercress is meant to be a perennial semi-aquatic vegetable.  Mine appears to be perennial, but then it self seeds so well that I am not certain that this is the case or if it forms a self sustaining population of annuals.  Regardless I always have some growing with minimal effort on my behalf, which is what I want.  Watercress is one of the oldest known vegetables, many of the older vegetables are semi-domesticated and can be a hassle to grow or harvest or eat or even have issues with edibility due to toxins.  While watercress could benefit from some serious breeding work to increase the size of the leaves, other than that it seem pretty good.  It is probably not great to eat in huge amounts, but I dare say one would eat a ridiculous amount before any problems would be noticed.  I dont think any brassica is fantastic to eat in huge amounts so it is certainly no worse than any of the others that people eat every day.  It handles cold weather, hot weather and does not appear to have any noticeable daylength sensitivity issues.

One place I grew watercress was in a fish tank as part of a mini aquaponics tank at work.  Water cress is clearly well suited to such life and performed well.  It appears that the only limiting factor here was sunlight, unfortunately my tank does not get quite enough light for it to perform as well as it should.  That being said it did well and cleaned the water well due to its rapid growth rate.  It did not take over the way mint does which is another bonus.  Unfortunately I did not take any pictures of this, it really does get very lush very fast with aquaponics.

Another way I grew it was in punnets.  I planted some seeds into a punnet of soil and kept this punnet in an icecream container with shallow water.  This was the simplest way to grow it that I could think of but I had doubts that it would grow using this method as the water is far from running.  I also grew some duck weed on top of the water (I like duckweed), this would lower the dissolved oxygen in the water so added to my doubts.  This grew incredibly well, these plants have since flowered and produced seed which I now need to collect and clean.  If I had limited space I would grow watercress in this way as it is so simple and productive.  The pot could be sized up or down to meet your needs and the ice cream container could be replaced with any container that holds water that is an appropriate size.

I have taken cuttings from the plants I was growing and put them in a glass of water.  In a few days they all grew roots at each node.  I tried to float a plant in some water in a fish tank and see if it would grow without soil.  Short term this went very well but eventually it all died off.  The lack of adequate sunlight was certainly a factor here but I think that water cress probably needs soil.

I am currently trying to grow some watercress in a bucket of soil that has a few cm of water on top of it in a similar way to water chestnuts and duck potatoes.  I took a cutting from the existing plants and have planted it in the bucket.  It is still early days but so far it appears to be growing well.  It has survived some frost as well as a few days with temperatures in the low 40s so is proving to be far more hardy that I would have expected.  I will try to remember to update this after they have been growing for a few months, if they do grow in this way it is even easier than the ice cream method above.

At this stage I do not sell watercress seeds but I may do so in the future if I ever get around to collecting enough seed.  If I do they will be listed on my for sale page with all the other perennial vegetables, heirloom vegetable seed and herbs that I sell.  Once you have some growing it is simple to keep it growing and propagate by taking cuttings.


UPDATE: the original plants were eaten out by slugs/snails/something in one night.  It seems odd they have grown for so long with no problems at all but then are completely gone in one night, but there is not much that can be done now.  I think it may have been water snails, but do not know for sure.  The cuttings growing in the bucket are so far untouched and are continuing to grow well.  This bucket has no water snails.

Freckles lettuce

Sometimes people give me vegetable seeds, they have different reasons for doing this, I dont always know why they do it but I do know that I really like it.  I particularly like it when I get surprise seeds from some dedicated seed saver.  Unfortunately I can not always grow every seed that I am given (although I certainly try my best) and sometimes I have to wait until the correct season to grow them, but only the best are kept from year to year.  One type of seed that I have recently been given is from an old heirloom variety of lettuce.

Freckles lettuce plants

I have never been overly fond of lettuce as it tends to be fussy and goes bitter at the drop of a hat.  Lettuce also tends to want to die, if there is anything around that eats plants the lettuce somehow calls it over for a munch.  The varieties I have grown in the past have required large amounts of water and weeding to deliver less than inspiring yields.  For these reasons I normally would not grow lettuce, but for some unknown reason I gave this one I go.

This variety is called "Freckles", it is an apple green variety with leaves that are uniquely speckled and splashed with deep red.  The pictures I took do not do it justice, the red is a lot darker in real life and the green more vibrant.  This plant has red blotches on top of the leaf as well as under the leaf.  Interestingly the blotches do not go the whole way through the leaf, the pattern on top of the leaf does not match the pattern under the leaf.

Freckles lettuce is a survivor!

It is mostly used as a loose leaf variety of lettuce.  I believe this variety can be cooked and used as a substitute for spinach but am yet to try that myself.  I like learning the history of the vegetables I grow, this one seems to have an interesting past.  From what I can gather it was originally a Dutch variety which was carried from the Netherlands to Canada by a Mennonite immigrant (named Urias Martin) in 1799.  Prior to that its history seems to have been lost.  I have also been told it was one of the lettuce varieties carried to Australia on the first fleet but unfortunately have not been able to confirm the accuracy of that claim.

I grow this lettuce mostly in the cooler weather, it does not appear to be bothered by frost.  I grew it in a bed where I thought it would have the best chance, unfortunately it is also a bed that had mustard plants flower and drop seed so the lettuce has to grow in amongst countless purple mustard volunteers.  Even with this high level of competition the lettuce performs rather well.

Being reasonably dry and hot I expected the lettuce to bolt to seed and go bitter, yet it seems to hold on ok and has not yet gone bitter.  Being so dry it is not growing as fast as it probably could, but it is still growing reasonably fast.  I would be interested to grow this using aquaponics and see how it can perform given ideal conditions.

Being a leaf variety rather than a head variety of lettuce means that we cut leaves as we need them and the plants keep on growing.  Any small or weak plants are removed so that only the stronger and better plants will eventually set seed.  Any plant that bolts to seed first is also removed so that slower bolting plants are the result.  Every time you save seeds you are adding selective pressure, I try to be conscious in selecting for traits that I find desirable so I end up with constantly improving stock.

What they taste like
One must keep in mind that this is a lettuce, so the taste will not blow your socks off.  I dont believe that any lettuce is truly remarkable as far as taste goes.  In my opinion lettuce is something you have with food, although it is certainly not bad for you it is not a food by itself.  Freckles lettuce tastes ok, it is not bitter or anything like that unless it is really a long way through flowering.  I guess I would describe the taste as pleasant and mild.  I have eaten many different home grown lettuces over the years and I would have to say that this one is my favourite.  I certainly plan to grow this variety every year as long as I have space.

I really should pull out some mustard

Where to get Freckles lettuce seeds
I will eventually try to sell seeds of Freckles lettuce, when I do they will be listed on my for sale page along with various other heirloom vegetables and perennial vegetables that I grow.  If I do not have it listed and you desperately want some seed let me know as I may have a little seed to spare.

Survivor Tatsoi

When we moved in here there were no vegetables, only empty vegetable beds, which was great.  Before we moved in there was a decent flood.  After we moved in we had another rather large flood.  A year or two passed, then a vegetable seedling grew in amongst the grass and weeds in the vegetable garden path.  It was from a vegetable that I have never planted, a seed that was here before we were.  I noticed it one day as I was mowing the weeds/grass in the vegetable garden.  I decided to mow around it as I liked its style.

This is one of the descendants of the mystery vegetable

That one determined little seed sat dormant through at least two floods, waiting patiently through several extreme summers, sat quietly through some cold winters, germinated in amongst tall grass and established weeds in a path that was trodden on several times a day by myself as well as my kids.  It then evaded being eaten by snails/slugs/poultry/birds/rodents and grew into an amazing little plant without a great deal of help from anyone.  This plant had earned my respect.

I wasnt terribly certain what it was to begin with, I knew it was some type of brassica.  I thought it was some form of Asian green, but having very little experience with them I did not know which one.  I gave it some water to keep it alive but generally forgot to water it.  I tried to gently pull some weeds near it but was scared of pulling it out too so left it to struggle against them.  The kids stepped on it a few times because it was growing in a rather inconvenient place.

More of my survivor tatsoi plants

I eventually figured it was most likely tatsoi.  I like the determination of this plant, it is a true survivor that beat the odds.  We ate some leaves but I let that single plant mature and flower, then I carefully collected the seed.

Brassicas tend to need other plants for cross pollination but I got a small amount of seed.  Many of the seed pods had no seeds, many of the seeds were too small to germinate, being so hot and dry the aphids covered the flowers at times, even with all this stacked against it the survivor tatsoi set a decent number of viable seed.  Quite often brassicas will have low or no germination if the population is too small, I had one individual and no other brassicas.  Things did not look good.  I planted a lot of the seed in the hope of enough germinating to get this strain going again and almost all of them germinated!

Brassicas also tend to suffer from inbreeding depression with small populations, so I did a large grow out from the seed collected from that single parent in the hopes of overcoming this.  So far the results appear to be pretty strong and healthy, I have not been able to see any lack of fitness and have a decent number of plants from here on.  I will be allowing all of these plants to flower and cross pollinate one another then I plan to collect seed from them all to maintain some small amount of genetic diversity.

What I have now is a strain of tatsoi that has overcome extreme hardship on pretty much every level.  I call it "survivor tatsoi" as I do not have any way to tell what cultivar it would have originally come from.  I hope to keep this strain going indefinitely from here on if I can.

I will probably be able to sell seeds of this tatsoi after the current batch flower/set seed and I test the seeds for germination rates.  I do not sell seeds if the germination rates fall to 85%.  When I do collect seed and test them they will be listed on my for sale page.
